Solution

1. Preparation

Gather tools (OBD-II scanner, coolant tester, socket set, multimeter, etc.).
Ensure the engine is cool before beginning work to avoid burns.
Disconnect the negative battery terminal to prevent electrical issues.

2. Coolant System Inspection

Remove the coolant reservoir cap and check the coolant level; add coolant if necessary.
Inspect the radiator cap for damage; replace if it's not sealing properly.
Examine hoses for leaks or wear; replace any damaged hoses.
Test the coolant for contaminants using a coolant tester; flush if contamination is found.

3. Thermostat Replacement (if faulty)

Drain the coolant from the system into a clean container.
Locate the thermostat housing and remove it using the socket set.
Take out the old thermostat and replace it with a new one, ensuring it is oriented correctly.
Reinstall the housing and torque the bolts to manufacturer specifications.
Refill the cooling system with the appropriate coolant mixture.

4. Radiator and Cooling Fan Check

Inspect the radiator for debris and clean it if necessary.
Start the engine and observe the cooling fans; they should activate when the engine reaches operating temperature.
If fans do not operate, test the fan relay and replace if faulty.

5. Final Assembly

Reconnect the negative battery terminal.
Start the engine and monitor the temperature gauge during idle and while driving.
Check for leaks around the thermostat and hoses after the engine has warmed up.
